The Volvo Penta 2-blade folding propeller is designed for engines between 5–40 hp and available in left-hand (for Saildrives) or right-handed rotation, generally used on a shaft. Volvo Penta folding propellers are available in multiple sizes and pitches for both Saildrives and shafts and they are made of extremely strong and durable Nibral (nickel-bronze-aluminium) alloy.
The Saildrive hub also has a shock-absorbing rubber bush to isolate it from the Saildrive and reduce stress on the gearbox caused by forward/ reverse gear changing. The hub also isolates the propeller from the Saildrive. Some aftermarket props can cause corrosion around the bearing housing by being electrically connected to the Saildrive shaft. A folding prop should always be isolated from the Saildrive, with its own anode.
Volvo Penta folding propellers improve the performance of your boat minimizing drag and increasing speed – up to 1.5 knots under sail, compared with a fixed propeller. In addition, the propeller profile also stops gearbox noise under sail, the risk of snagging ropes and nets when sailing.
At 6 knots, for example, a 2 blade fixed propeller produces more than five times the drag of a 2 blade folding propeller. This means a typical journey across the English Channel can be reduced by up to 4 hours thanks to lower drag.
Please note a hub kit is required to complete the installation.
